I'm putting together one good Colour Classic, from parts of three CC Carcasses...Here's a video glitch...When it boots up, the picture has a green tint..colours look washed out...When I give it a slap on the left side of the CC.towards the back...The tint problem goes away..and the picture looks normal..until it does it again...Once I slap it, again problem ceases.

woukd like to fix this, and stock pile some CC parts..in case one day, she decides to take the day/week/month/year off..
Successful slappage tells you that it's most likely a loose connection. These are easily fixed -- the tricky part is finding them. Look for bad solder joints. Freshen up any of them that look suspicious. Disconnect connectors, inspect and clean if necessary, and reassemble. In your case, pay special attention to the CRT socket itself (not the HV "suction cup" connection -- I mean the socket at the rear of the CRT). A little investigation, and you should be able to get that one to behave.

good points...and I suspected as much....Most problems with our CC and other similar compacts are glitches like this. Most are connections and joints that need to be 'refreshed' or so on...I guess these machines are far exceeding their operational lives..and hence some of these 'new' problems. did anyone at APPLE, ever remotely think that 1993's Colour Classic, would be in service, in 2008...15 yrs down the time line ...same goes for our beloved compacts like the PLUS, SE, etc....

The trick is to take time, and slowly track these problems down...and if possible, stock pile several 'donor' compacts, for needed parts...

Myself, have done this..including some decent burn free CRTS from SE's & Plus..I've seen some badly burned in tubes..complete with images burned in 'em..forever.....MB's and Analog boards are worth stock piling, as well as some of those SE power supplies...( sony etc )

Great that we can access a forum like this to help keep our little friends alive...
